Question

(a) use the calculator to find the perimeter and area of the parking lot. make sure to include the correct units. perimeter: area: (b) a chain will surround the lot. which measure would be used in finding the amount of chain needed? perimeter area (c) the lot will be paved. which measure would be used in finding the amount of pavement needed?

Explanation:

Step1: Recall perimeter formula for rectangle

For a rectangle with length $l = 80$ yd and width $w = 60$ yd, the perimeter formula is $P=2(l + w)$.
$P = 2(80+60)$

Step2: Calculate perimeter

$P=2\times140=280$ yd

Step3: Recall area formula for rectangle

The area formula for a rectangle is $A=l\times w$.
$A = 80\times60$

Step4: Calculate area

$A = 4800$ yd²

Step5: Determine chain - related measure

The amount of chain needed to surround the lot is given by the perimeter.

Step6: Determine pavement - related measure

The amount of pavement needed is given by the area.

Answer:

Perimeter: 280 yd
Area: 4800 yd²
(b) Perimeter
(c) Area
